Olsen to film De Niro project during school break

The twins' 21-year-old sibling is making a name for herself in Hollywood, following her debut in Martha Marcy May Marlene, but she is refusing to sacrifice university for her burgeoning film career.

Olsen, who is studying psychology at New York University, will put her education on hold to shoot director Rodrigo Cortes' upcoming thriller with De Niro, Sigourney Weaver and Cillian Murphy, but she's adamant her classes will always come first.

She tells the Hollywood Reporter, "Robert plays a world renowned psychic and Sigourney is a psychology professor, and I play her student. Cillian Murphy is my love interest, though that's not a huge part of the story.

"I'm so lucky that school is always there for me when I take these little breaks. But my education is always a priority."
